In a reply to our letter Ferrandiz and colleagues wondered why dermoscopy experts did not already fully embrace teledermoscopy (TD) for suspicious pigmented skin lesions.(1) Our study showed that the structure of the health systems that were investigated differed, with countries where primary care physicians (PCP) hold a gate keeper function and others with direct access to a dermatologist. Significant differences in waiting time and travel distance were observed.(2) Since we believe that there is enough evidence that the addition of high quality dermoscopic pictures to a teleconsultation leads to higher accuracy of the diagnosis we did not investigate this question in our survey...

BACKGROUND: Dermoscopy is a noninvasive diagnostic technique that allows visualization of structures of the superficial dermis not visible with the naked eye. HYPOTHESIS/OBJECTIVES: To assess the usefulness and applicability of dermoscopy for evaluation of healthy equine skin. ANIMALS: Twelve healthy horses from a research herd. METHODS: Five regions (cheek, lateral neck, dorsum, flank and abdomen) were examined with contact dermoscopy using both nonpolarized and polarized light at both 17-fold and 24-fold magnification...

<p>Amelanotic melanoma (AM) is one of the great masqueraders in dermatology. It is a very difficult clinical diagnosis to make because these tumors are devoid of pigment and other clues of melanoma. They are commonly misdiagnosed clinically as other benign and malignant conditions. We present a new case of AM in an 84-year-old woman with a history of non-melanoma skin cancer. She had a thin pink plaque that was initially misdiagnosed as a basal cell carcinoma. We also discuss dermoscopy and its valuable role to improve diagnostic accuracy...

BACKGROUND: Shiny white streaks (SWS) are best visualized with polarized dermoscopy, and correlate with dermal fibroplasia histopathologically. SWS have been described at higher frequencies in melanomas than benign nevi. OBJECTIVE: We assessed the diagnostic value of different patterns of SWS and their histologic correlate in melanocytic lesions. METHODS: Polarized dermoscopic images of 1507 histopathologically diagnosed melanocytic neoplasms were analyzed for presence and pattern of SWS...

BACKGROUND: Nevi of special sites encompass a class of benign lesions characterized by the presence of atypical clinical and histopathologic features that can be difficult to distinguish from melanoma. Dermoscopy and reflectance confocal microscopy may improve the clinical assessment of melanocytic lesions in order to avoid unnecessary excisions. OBJECTIVES: The aim of this study was to assess the value of specific dermoscopic and confocal criteria in distinguishing melanomas from nevi of the breast area...

BACKGROUND: Reflectance confocal microscopy (RCM) is an imaging device that permits non-invasive visualization of cellular morphology and has been shown to improve diagnostic accuracy of dermoscopically equivocal cutaneous lesions. The application of double reader concordance evaluation of dermoscopy-RCM image sets in retrospective settings and its potential application to telemedicine evaluation has not been tested in a large study population. OBJECTIVE: To improve diagnostic sensitivity of RCM image diagnosis using a double reader concordance evaluation approach; to reduce mismanagement of equivocal cutaneous lesions in retrospective consultation and telemedicine settings...

BACKGROUND: Pigment network is an important dermoscopic features for melanocytic lesions but alterations in grid line thickness are also observed in melanomas. OBJECTIVE: To investigate features of thick, thin and mixed pigment networks at dermoscopy and their respective features at Reflectance Confocal Microscopy (RCM) for differential diagnosis, correlated with histology METHODS: All melanocytic lesions with histological diagnosis, evaluated between January 2010 - May 2014, were enrolled and classified according to dermoscopy evaluation of the pigment network; thin, thick and mixed...

BACKGROUND: Nail matrix histopathological examination is essential to diagnose longitudinal melanonychia (LM). Several methods for nail matrix biopsy have been introduced but are often difficult to perform because of their invasiveness and technical difficulty. Therefore, a less invasive and novel biopsy technique is needed. OBJECTIVE: To introduce a window technique for nail matrix biopsy. MATERIALS AND METHODS: We retrospectively reviewed the medical records and histopathological specimens of patients with LM who underwent the window technique for nail matrix biopsy at our institution between September 2015 and December 2016...

BACKGROUND: Clinical distinction between nail matrix nevus (NMN) and subungual melanoma (SUM) can be challenging. More precise delineation of the clinicodermoscopic characteristics specific for NMNs is needed. OBJECTIVE: We sought to analyze the clinicopathologic features of childhood and adult NMNs and to propose clinicodermoscopic features that can aid in differentiating NMNs from SUM. METHODS: We retrospectively reviewed clinical, dermoscopic, and histologic findings of patients (20 children and 8 adults) in whom NMN was diagnosed between 2012 and 2015...

BACKGROUND/OBJECTIVE: To describe the dermoscopic features of melanoma in situ using the Chaos and Clues method. METHOD: Histologically proven primary melanoma in situ (MIS) diagnosed through a specialist teledermoscopy clinic were reviewed by three dermatologists. By consensus they agreed on the global dermoscopic pattern, colours, presence of chaos (asymmetry of colour and structure and more than one pattern), and each of the nine clues described for malignancy...

BACKGROUND: Dermoscopy is a diagnostic tool that has been introduced into small animal dermatology for the evaluation of hair and the skin surface. To the best of the authors' knowledge, the use of this technique on horses and the dermoscopic appearance of equine hair and skin have yet to be reported. HYPOTHESIS/OBJECTIVES: To assess the feasibility of dermoscopy, and to describe hair and skin surface features of healthy warmblood horses. ANIMALS: Thirty four client-owned, healthy adult horses...

BACKGROUND: Onychomycosis is one of the most common diseases of the toenails. The costs of diagnosis and treatment are substantial, and as the population ages, the overall cost burden will continue to escalate. The purpose of this study was to correlate dermoscopic features with pathologic diagnosis to support the accuracy of point-of-care diagnosis by dermoscopic examination. METHODS: Nail unit pathology reports of 52 patients with abnormal great toenails were compared with the dermoscopic features detected by nail unit dermoscopy...

BACKGROUND: Vitiligo is essentially a clinical diagnosis, and dermoscopy may aid in noninvasive confirmation of diagnosis by excluding other clinically simulating hypopigmentary conditions. More importantly, dermoscopy is rapidly gaining ground as an important adjunct tool to evaluate disease activity. AIM: To study the dermoscopic features of vitiligo and ascertain their correlation with disease activity. METHODS: Retrospective analysis of dermoscopy of 60 cases suffering from vitiligo was undertaken...

BACKGROUND: The clinical outcome of teledermatology with dermoscopy in large-scale primary care networks remains unclear. OBJECTIVE: We evaluate the impact of implementing a teledermatology consultation program with dermoscopy on a statewide scale, focusing on access to care and skin cancer screening for medically underserved populations.

BACKGROUND/PURPOSE: Mohs Micrographic Surgery (MMS) is the preferred therapeutic treatment for high-risk basal cell carcinoma (BCC). Optical Coherence Tomography (OCT) is a non-invasive imaging technique that enables the diagnosis of BCC. We thought to determine the margins of BCCs with OCT, prior to MMS, to reduce the number of surgical steps. METHODS: Different permanent markers were tested on the skin regarding line width, resistance against disinfection and brightness in the OCT image...

BACKGROUND: Recently, it has been shown that reflectance confocal microscopy (RCM) could identify subclinical basal cell carcinoma (BCC) during vismodegib treatment of locally-advanced BCC. OBJECTIVES: To evaluate specificity and sensitivity of clinical, dermoscopic and RCM examination for BCC in patients with multiple BCCs treated by vismodegib. METHODS: 94 BCCs had 710 clinical, dermoscopic and RCM examinations during 72 weeks of vismodegib treatment...
